Specification of Letters Patent.

Patented Oct. 21, 1919.

Application filed February 18, 1918. Serial N 0, 217,973.

To all whom it may concern:

Be it known that I, JOHN EARL Boon, a citizen of the United States,residing at York, in the county of York and State of Pennsylvania, haveinvented certain new and useful Improvements in Mechanically- OperatcdSettling Devices, of which the following is a specification.

One object of my invention is to provide a mechanically operated devicefor jolting or settling down in a compact or solid mass granularmaterial, such as sand, cement, etc., or in fact any material whichconsists of separate particles or pieces.

Another object is to make my invention of simple and durableconstruction and so that it will take comparatively little power tooperate it. Y

These objects, and other advantageous ends which will be describedhereinafter, I attain in the following manner, reference being had tothe accompanying drawings in which- Figure 1 is a top plan view of adevice setting forth one embodiment of my invention,

Fig. 2 is an end elevation of Fig. 1,

Fig. 3 is a side elevation of the device shown in Figs. 1 and 2,

Fig. 4: is a sectional view taken on the line 4+4: of Fig. 1,

Fig. 5 is a fragmentary perspective view showing ceitain of the parts ina'diiferent position from that illustrated in Figs. 1 to 4, inclusive,and 3 Fig. 6 is an end elevation of similar nature to Fig. 2 butincluding a modification of certain of the elements.

Referring to Figs. 1 to 5, inclusive, of the drawings, 1 represents abase structure which may be made in the form of a hollow frame having aflat top :2 uponwhich normally rests a movable support 3. This support 3may be in the form of a table or platform, as illustrated, and I haveshown a flask, tray, or other container 41 resting 011 said movablesupport, and for example may be considered as filled with sand formolders or foundry use and which it is desired to jolt or settle into amore compact 01" solid form. The base structure 1 has two extensions 5and these extensions at their outer ends form bearings for a shaft 6,said shaft having a pulley 7 thereon by which it is rotated, and alsoincludes two cranks 8.

Two fulcrumed members 9 are positioned at opposite ends of the basestructure and, as illustrated, are in the form of double ended leverswhich are pivoted to the base structure 1, as illustrated at 10. Thelevers 9 have their ends 11 included in the planes of movement of therespective cranks 8 and each of the cranks 8 is preferably provided Withan anti-friction roller 12 adapted to engage the upper edge surface ofthe ends 11 on the respective levers 9.

The opposite ends of the levers 9 are pivotally connected at 13 to links1 1, said links being pivotally connected at 15 to opposite ends of themovable support 3.

The movable support 3 has guiding rods or plungers 16 dependingtherefrom and adapted to slide within vertical slideways 17 provided bythe base structure 1.

Considering that the shaft 6 rotates in the direction of the arrow shownin Fig. 2 and that the movable support 3 is in its normal position,resting on the base structure 1, the operation is as follows: The cranks8 will straddle the ends 11 of the respective levers 9 until theanti-friction rollers 12- engage the top edges of said lever ends 11,

- such position being illustrated in Figs. 1 to 4:, inclusive. Acontinued movement of the shaft 6 in said direction will cause thecranks to move the ends 11 of the levers 9 downwardly on the pivotalfulcrums 10 and at the same time the opposite ends of the levers 9 willbe raised to effect the raising of the movable support 3, the latterbeing guided during its raised movement by the plungers 16 within theslideways 17 This raising of the movable support 3 will con tinue untilthe levers 9 have been moved into such position that the cranks willfree or pass by the ends 11 after which the movable support 3 and thetray twill fall by gravity until said movable support is stopped byengagement with the upper surface of the base structure 1. This suddenstopping of the movable support will cause the material within thecontainer 4 to be jolted and. settled down into a compact mass and itwill be noted that the extent of this settling of the material with-inthe con tainer'a can be varied according to the number of times that themovable support 3 is permitted to fall.

It will be further noted that for each rotation of the shaft 6 thelovers 9 will he actuated and freed by the cranks 8 so that during thetime when the levers 9 are not under control of the cranks 8 the movablesupport will have time to fall, as above dc scribed. V

In the construction shown in Fig. 6, instead of a link connectionbetween the pivots 15 and 13, as described in connection with Figs. 1 to5, inclusive, I provide the opposite ends of the movable support 3 withantifriction rollers 18 so that the ends 19 of the levers 9 engage thebottom of the peripheral surfaces of these rollers and thereby effectthe raising of the movable support 3. Also in this construction Iprovide a stop 20 7 under each end 19. of the levers 9 so that when thelevers are not under the control of the cranks 8 they can fall and restupon the stops 20. In all other respects the construction shown in IFig.6 is similar to that described in connection with Figs. 1 to 55,inclusive, and I have, therefore, given similar parts correspondingreference numerals. Furthermore, While I have illustrated but one endview of the modification shown in Fig. 6, it will be understood that theopposite end of the device is similarly constructed and includes a stop20 and an anti-friction roller 18.

. My invention is well adapted for use in foundries for the making ofmolds for cast ings or cores and the sand can be settled down to thedesired compactness. Also my invention is well adapted for use infactories or manufacturing plants of various types where articles, suchfor example as bullets or shot, are required to be settled within shellcasings, etc., and for many other purposes. While I have described myinvention as taking a particular form, it will'be understood that thevarious parts of my invention may be changed without departing from thespirit thereof, and hence I do not limit myself to the preciseconstruction set forth, but consider that I am at liberty tormake suchchanges and alterations as fairly come within the scope of the appendedclaims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In a device of the character described, a rotatable shaft having anintegral crank thereon forming an interruption in the axial portion ofthe shaft; a movable support; and a fulcrumed lever, said crank duringthe rotation of the shaft being initially operative to straddle one endportion of said lever to move said lever to raise the movable support,said crank during a por- Gopies of this parent may be obtained for tionof its 7 continued movement being adapted to free said end of the leverto permit the movable support to fall by gravity, substantially asdescribed.

2. A device of the character described including a rotatable shafthaving an integral crank thereon located within its length and formingan interruption in the axial'portion of the shaft; a movable support;and a fulcrumed lever, said crank during the rotation of the shaft beinginitially operated to straddle one end portion of said lever to movesaid lever to raise the movable support, said crank during a portion ofits continued movement being adapted to free said end of the lever topermitthe movable support to fall by gravity, substantially asdescribed.

3. In a device of the character described, a rotatable shaft having acrank thereon forming an interruption in the axial portion of the shaft;an anti-friction roller on the portion of said crank which is remotefrom the axis of said shaft; a movable support; and a fulcrumed lever,said crank during the rotation of the shaft being initially operative tostraddle one end portion of said lever to permit said anti-frictionroller to engage said lever and to move said lever to raise the movablesupport, said crank during a portion of its continued movement beingadapted to free said end of the lever to permit the movable support tofall by gravity, substantially as described.

4. A device of the character described including a rotatable shafthaving a plurality of integral cranks thereon forming interruptions inthe axial port-ion of the shaft; a base structure; a plurality offulcrumed levers; and a movable support normally resting on the basestructure and adapted to' be raised by said fulcrumed levers when thelatter are moved on their fulcrums, said cranks on the shaft beingrespectively adapted to straddle said levers and move them ontheirfulcrums to raise said support, said levers being of .such length as tobe freed by said cranks after they have moved a certain distance topermit the movable support to fall by gravity upon said base structure,substantially as described.

In testimony whereof I have signed my name to this'specification inthepresence of two subscribing witnesses.
